Burqaawwan dalgee yeroo dhiibaman daayameetiraan waan babal’ataniif, malli balaliisaa (giddugaleessa) murteessaadha. 'Shaft Piloting' tiif, $D_{in}$ birraa qindaa'inaaf fayyadama. Daayameetiriin shaafta $D_{shaft}$ akka $D_{shaft} < D_{in(min)} - \text{Contraction}$ guddifamuu qaba. 'Bore Piloting' tiif, $D_{out}$ birraa fayyadama. Daayameetira boora $D_{bore}$ $D_{bore} > D_{out(max)} + \text{Expansion}$ ta'uu qaba. Walumaagalatti, bore piloting springs Crest-to-Crest tiif filatamaadha sababiin isaas springn sun osoo frictional binding shaft irratti hin hidhamin bilisaan akka babal’atu waan taasisuufi, kunis osoo akkas ta’ee hysteresis gara load-deflection curve seena.
